REGENT STREET, CLOUCESTER- 



AT a Meeting of the ENTOMOLOGICAL SECTION of the Yorkshire 

 Naturalists' Union, held at Leeds on January 11th, it was decided to 

 pubrsh a LIST, with localities, &c., of the Lepidoptera of the county of 

 York. Its compilation was placed in the hands of Mr. W. Prest, of 

 York, and myself. May I ask, thf refore, that every lepidopterist who has 

 collected in any part of Yorkshire will kindly send hst with localities of all 

 the species noticed, with any notes that may be of use, to me, as early as 

 convenient. I need scarcely say that all such assistance shall be fully 

 acknowledged.
